Marsupialization and functional obturator placement for treatment of dentigerous cyst in child: A successful blend

Abstract

The Dentigerous Cysts (DCs) are considered the most common developmental Odontogenic cysts (OCs), they are related to the crown of unerupted impacted tooth. These cysts are usually asymptomatic; however, some cases complain of facial asymmetry, teeth displacement, root resorption of adjacent teeth, and pain if inflammation occurs. Radiographic examination usually reveals a unilocular radiolucency with sclerotic borders and surrounding the crown of an unerupted tooth. Classically, DCs are treated with enucleation and extraction of the involved tooth. However, owing to the high prevalence of these cysts in children, marsupialization is followed as a line of treatment that permits the eruption of the permanent tooth involved. This article presents a case of left mandibular DC in a 7.5 years boy. Marsupialization was the treatment modality chosen with a precisely fitted functional and removable acrylic obturator provided, where a 12-months follow-up revealed complete uneventful healing of the lesion alongside eruption of the involved tooth.
